in order to afford the requisiteu'igidity to the standards 28 and 29 audto frevent their s reading under'j the stl-esa r'ol-v supporting tileload, I,prefe'rably provideo liquely'dis posed stay-rods 32 and *33connected to the socket members'24 and 25 and to thestand:

To facilitate the rotary movement of the'liftingelements as ju'st'described, I have found it expedient to provide eachstandard at its-lowefex tremity with a wheel or roller, such', forexample, as shown in Fig.5, wherein :ncaster 35 having a shank. 36 .thestandard37 'iseinployed, a cotter pin 38 the revolution of the Seated'.inthe base'of passlng'through the exposed portion of the a shank of thecaster dislodgment thereof.

such as'illustrated in Fig. 5, when the vehicle has been jacked up, asshown in Fig. 4, it may be readily moved in any direction to facilitatestorage, cleenin and the like. in the latter connection, if esired, theveunauthorized use by locking the pawl 40 in engagement with the ratchet39 by meens'of a pad-lock, shown at 45, passing throu h e as 46 an '47;as shown in Fig. 7. y t is means, it will be evident that no one butpossessing the key to the lock will torestore the lifting elements tomake use of the'vehicle,

There are many other avenues of use for my invention and it is obviousthat there may be immy changes made in structural details withoutdeparting from the spirit and scope of my invention, the applicationherein shown being simply employed for the purpose of furnishing a clearand comgmal iensi ve description.
